I have to agree with the above but they do have there place I`v got 2 FAC Rapids 177&22 945fps in both 10.5 and 18gr zero at 45 yards and take out to yards no problem , people I know do longer but I leave that for my 17HMR, the difference between 177 and 22 is after 50 yards the 22 drops more ,but if you sell the 22 will shift better.If you fancy a drive meet up and I`ll take you out to try.
